Elevated blood pressure in young adults associated with middle-age heart issues Young adults who had blood pressure that was elevated but still within normal range for long periods of time were more likely to show signs of cardiac dysfunction in middle age, according to a study
Blue light sets the beat in biological pacemaker Using optogenetics, researchers have established a new approach for pacing the heart and synchronizing its mechanical activity without a conventional electrical pacemaker. This finding could help avoid many drawbacks of electrical pacemakers.
Cell that replenishes heart muscle found by researchers Regenerative medicine researchers have identified a cell that replenishes adult heart muscle by using a new cell lineage-tracing technique they devised. Adult heart muscle is comprised of cells called cardiomyocytes. Most cardiomyocytes don't replenish themselves after a heart attack or other significant heart muscle damage. The new cell-tracing technique allows them to detect cells that do replenish themselves after being damaged.
Current monitoring of pacemakers, defibrillators may underestimate device problems The current monitoring of patients with cardiac implantable electronic devices such as pacemakers and defibrillators may be underestimating device problems, according to researchers who propose systematic methods to determine accurate causes of sudden death in those with CIEDs as well as improved monitoring for device concerns
Heart patients can stop blood thinners when undergoing elective surgery Patients with atrial fibrillation who stopped taking blood thinners before they had elective surgery had no higher risk of developing blood clots and less risk of major bleeding compared to patients who were given a "bridge" therapy, according to research.
